CD recoverable? Ideas?

[KVandal]

Got a CD which worte perfectly and then read perfectly. After 3 weeks in a case, it is needed, and consequently, seems to have gone tits up.

Windows complains of cyclic redundancy errors and bad sectors, and it has been tested in several drives inc:
liteon
dell pc
some 4x drive with no name
and a couple of others, i forget.

Any ideas on recovering them? some of the data reads, but the mojority doesnt and this is critical data :/

Any help much appreciated!

If you have CloneCD try to make a copy?

Just an idea....

try getting a program called 'isobuster' see if you can get the data out using that.. not ideal tho.. i take it you are trying the cd in the same drive you used to burn it? some cd-drives are fussy with cd-r and such media

crc errors mean u wont be able to read it properly, depending on whats stored on it, it might not matter, but i think theres ways to get to the data...

data cds usually have error checking, which is done by CRC
vcds and svcds though, dont, so ther emight be a way to trick it into thinking its one of them, and reading it (vcd/svcd cds can be read in windows like normal cd's)

Get some software like alcohol

make an image of the CD using alcohol and set the copy protection to somthing like safedisk (where there are supposed to be read errors on the CD)

Mount the image so you can see the files

Any files that dont have errors in them you will be able to drag and drop to your desktop / somwhere on your HD. The files that are corrupted you wont be able to copy off the virtual drive. Even if you do though, they wont work.

That should allow you to try and salvage as much as you can. If that doesnt work, cant see any other ways im afraid

i assume the errors are only on some files, ive had it before.. if its on the hole disk, hten no chance of any files being fine, some corruption might not matter though, like with mpegs etc..

[KVandal]

yes, errors only on some files. albeit a large number of them.

Will have a go at some of that stuff when my comp gear arrives (if ebuyer ever get their thumb out of their arse). In the meantime, ill keep trying

Tx again.

Pay a company that specialises in this kind of thing to recover the data for you? Depends how critical (or pornographic ) the data is as to whether it's worth it or not, of course, but a quick google suggests that many of them will evaluate the disc for free.

Incidentally one of my mates started having CRC errors on most of the discs he wrote and ended up RMA-ing the drive (which had been working fine up until then). You might want to take a look at yours, if it's a relatively new drive.
